Limit the tenure of any speaker of the House of Commons to a maximum of 7 years

While a speaker can face a formal challenge immediately after a general election, traditionally sitting speakers are not challenged. Once in post there are few legal mechanisms for his/her removal other than trying to persuade him/her to resign. Until such time as Parliament devises new ways to ensure the Speaker's role is held accountable, it is important that we limit the tenure of this role.
